Cart detection is safer: distinct amounts in one label are no longer treated as the order total, and the coupon field and Apply button must belong to the selected cart. When checkout evidence is ambiguous, ShopTools does not start testing or claim a discount. No new permissions.

Version 4.45 improves checkout coupon verification. A code is only confirmed when the final payable total decreases and the result stabilizes. Store acceptance text alone is not treated as verified savings. Improved handling of changing totals, currency mismatches and interrupted checks. Coupon availability and savings still depend on the store and basket.
